A mod to auto merge imported usernames

[Nick1337]

I imported a backup and i need to know if there is a mod that will automatically merge usernames like imported_username with username automatically?

Assuming you used ImpEx, then all accounts that could be merged are already merged (if username and email address match).

I used impex, but usernames arent merged or nothing, when they should be

[Marco van Herwaarden]

Then the email addresses did not match, as ImpEx with the default options would do this automatically.

Ok, so how can i merge them automatically cuz i have many of them
